SMUT-MACI-IINE.

Specification of Letters Patent No. 8,904, dated April 27, 1852.

` To all 'whom 'it may concern:

b Troy, in the county of Rensselaer and State of New York, have inventeda new and Imw proved Machine for Cleaning Grain; and I do hereby declarethat the following is a full and exact description thereof, referencebeing had to the accompanying drawings and to the letters of referencemarked there on, viz.:

Figure l is a sectional elevation of the en tire machine. Fig. 2 is aground plan and elevation of the rubber and ventilator cut through themachine at A, B. a, a, a, a are two sets of spiral arms, one set in theventilator and the other in the rubber and are made in this form tocreate a center draft of air for the purpose of driving the chaff and`slnut downward to the discharge spouts.

Fig. 3 is a ground plan and elevation of the scourers, beaters, wingsand part of the rubber. The ground plan in this figure is a view of thebottom scourer seen from the lower side. B, B, B, B are four wings eX--tending from the lower scourer to the rubber. These wings are for thepurpose of driving the dust and other light stuff through the smallopenings in the outside or case. c, c, c, c are the beating forksattached to the scourers. These arefor the purpose of breaking orbeating the hulls and such other substances as Vadhere to the berriesafter having been discharged from the rubber. D D are two Scrapersattached to the under side of the lower scourer. These Scrapers gatherthe grain as it falls upon the center plate and force it out of theopenings in this plate on to the screen aprons.

Fig. 4L is a ground plan and elevation of the blower which runs in thebot-tom. This blower is made very large for the purpose of producing astrong blast which comes in contact with the grain upon the screens.Fig. 5 is a ground plan and elevation of the concave bottom with the topor body of the machine removed so that the screens and aprons can beseen. e, e, are the screens and aprons which are united and fastenedinside of the screen chambers and extending upward to the openings inthe middle plate.

y The screens do not cover the whole of the screen chamber but anopening is left sufficient to let the grain pass over when it slideslower bearing of the shaft. But

down the chamber and discharges at the bottom of the machine. `f is abridge pot that the lower end of the shaft runs in. G is the oil pipewhich supplies the step with oil from the outside of the machine. Theelevation in Fig. 5 shows the bottom cut though at the line I-I H andexhibits the in* s1 e.

Fig. 6 is a ground plan and elevation of one half of the case removedfrom the machine. z is the journal and oil boX. c', i are the frameswhich project from the bottom plate and set upon the edge of the screenchambers and form a base for the smut spouts. j, j, are the openingswhich admit the grain into the machine.` The elevation in this ligure isan insidevview of the case. 7c, k, are a series of circular zigzaggrating projections upon the under side of the head plate which works inunison with the rubber which rub and grate the berry before coming incontact with the beating and scouring surfaces.

Fig. 7 is an elevation of `the entire machine with the smut spoutsattached. These spouts are provided with openings near the top and aslide for opening or closing the same for the purpose of increasing ordiminishing the blast. These smut spouts are shown on Figs. l and 7 andare marked W. The smut chaff and other light stu is blown out, alltogether, `through the smut spouts fw, fw and the grain passes over theend of the screen e and discharges through the bottom.

Thus having fully described my machine I wish it to be understood that Ido not claim as new a perforated case the same having been heretofore inuse, neither do I claim a spike rubber nor a ventilator with spiralarms, nor scourers made of sheet or other metal, nor do I claim the oilbox at the top of the machine nor the oil pipe for the What I do claimas new and desire to secure by Letters Patent is 1. The projectingscreen chambers,in combination with the arrangements for separating therubbing chamber from the fan chamber, whereby the grain is preventedfrom being affected by the blast from the fan chamber, while it ispassing through the rubbing chamber, and is only brought in contact Withthe current of air Where it asoende to the soourers, whereby the berriesare more take away the oha and. other lmpurities efi'ectually cleanedfrom adhering impuri- V substantially as herein set forth. ties asherein set forth.

2. I also claim in combination with the JOHN M. EARLS. v 5 scouringsurfaces, the beating forks, orvthe Witnesses:

' purpose of beating the grain and breaking E. BELL,

the hulls While falling from the rubber to JOSEPH HYDE.
